The explanation is this: Rehab is the name of the ongoing mega-party Sundays at Las Vegas’ Hard Rock. So you know, it’s not really “rehab,” kind of the way the kids used to say “You’re so baaad” when they really mean “You’re so gooood.” (In other words, don’t hold out for the companion series suggested by my Variety colleague Michael Schneider: “Sex Addiction Rehab: Party at the Spearmint Rhino.”)

I’m probably the last to know about the Vegas version of Rehab, but my summer Sundays do tend to involve a much smaller pool — about 18 inches deep and made of hard plastic — rather than giagsmic blowouts with a different demographic. In any event, while “Rehab” has been renewed for a third season, I do await the inevitable sequel: “Rehab: Rehab From the Party at the Hard Rock Hotel.”
